Paul McCartney Stuns London Crowd With Surprise Dave Grohl Reunion — Before Performing One of His Strangest Solo Songs Live for the First Time in 35 Years

Paul McCartney already had a major surprise waiting for fans at London’s O2 Arena when Dave Grohl unexpectedly walked onstage.

But even a reunion between the Beatles legend and Foo Fighters frontman wasn’t the night’s only piece of rock history.

McCartney also reached deep into his solo catalogue to perform “Temporary Secretary” live for the first time ever — 35 years after the eccentric McCartney II track was originally released.

Together, the two moments turned Saturday’s concert into a night built around old friendships and songs McCartney’s audience could hardly have expected to hear.

Dave Grohl Walks Out for a Beatles Classic

Grohl joined McCartney for “I Saw Her Standing There,” the explosive opening track from the Beatles’ debut album.

Their previous collaborations have frequently put Grohl behind the drums.

This time was different.

The Foo Fighters frontman stood alongside McCartney at the front of the stage, playing guitar and joining the chorus as the pair tore through the Beatles favorite.

It was another chapter in a musical friendship that has repeatedly brought the two generations of rock together.

And “I Saw Her Standing There” already has special history between them.

They First Played the Song Together at the Grammys

McCartney and Grohl previously performed “I Saw Her Standing There” together at the 2009 Grammy Awards.

On that occasion, Grohl was behind the drum kit.

Their relationship later produced something even more unexpected.

McCartney joined Grohl, Nirvana bassist Krist Novoselic and Foo Fighters guitarist Pat Smear to record “Cut Me Some Slack” for Grohl’s Sound City documentary.

The track went on to win a Grammy.

For McCartney, however, the experience of playing with the surviving Nirvana musicians had another significance.

“It was magic for me playing with these guys,” McCartney told Rolling Stone in 2014.

He recalled Grohl telling him that “a couple of friends” would be joining the session before McCartney realized exactly what was happening around him.

“And during the session I hear them talking: ‘Wow, we haven’t played since Nirvana.’ So I found myself in the middle of a Nirvana reunion.”

When asked back then whether he and Grohl might perform together again, McCartney offered a tantalizing answer:

“You never know.”

Saturday night proved him right.

McCartney Had an Even Rarer Surprise Waiting

As unexpected as Grohl’s appearance was, McCartney delivered something during the same concert that had never happened before.

He performed “Temporary Secretary.”

Released on 1980’s McCartney II, the frantic electronic track is one of the strangest entries in McCartney’s enormous catalogue.

Built around a relentless synthesizer pattern, the song sounds dramatically different from the melodic Beatles classics for which McCartney is best known.

Rolling Stone has previously described it as both an “insane highlight” of McCartney II and one of McCartney’s 12 weirdest songs.

Yet despite surviving as a cult favorite for decades, it had never made it onto a concert stage.

Until now.

35 Years Later, ‘Temporary Secretary’ Finally Gets Its Live Debut

McCartney waited approximately 35 years after the song’s release before finally performing “Temporary Secretary” in concert.

And rather than dramatically reinventing it for the stage, the live version reportedly stayed remarkably faithful to the eccentric original recording.

Its appearance also continued a pattern developing on McCartney’s tour: songs that had spent decades untouched were suddenly finding their way into the set.

He had already delivered another historic first by performing the Beatles’ “Another Girl” as a solo artist.

That song originally appeared on the Beatles’ 1965 album Help!, but McCartney had never previously performed it live as a solo artist.

Now “Temporary Secretary” has joined the growing list of deep cuts receiving an unexpected second life onstage.

An Unlikely Friendship That Keeps Producing Rock History

The chemistry between McCartney and Grohl has always crossed an unusual generational divide.

One helped define popular music with the Beatles.

The other emerged decades later through Nirvana before leading Foo Fighters.

Yet their paths have repeatedly intersected — from the Grammys to Sound City and now another spontaneous-looking appearance in London.

For McCartney, their Sound City session was particularly memorable because he effectively found himself playing inside an unexpected Nirvana reunion.

For Grohl, collaborations with a Beatle have allowed him to move between instruments and roles.

He was McCartney’s drummer at the Grammys.

He was part of the band behind “Cut Me Some Slack.”

And at the O2 Arena, he stood beside McCartney with a guitar and helped sing one of the Beatles’ earliest rock ‘n’ roll classics.

One Concert, Two Completely Different Trips Into McCartney’s Past

The surprises couldn’t have been more different.

“I Saw Her Standing There” returned McCartney to the beginning of Beatlemania, with Grohl beside him giving the 1963 song another cross-generational rock moment.

“Temporary Secretary,” meanwhile, transported the arena to McCartney’s experimental 1980 period — a song so unusual that even after three and a half decades, he had never attempted it onstage.

One was an enduring Beatles classic shared with an old friend.

The other was a strange solo deep cut finally escaping the studio after 35 years.

For an artist with more than half a century of songs to choose from, McCartney once again proved that even the most familiar catalogue in rock can still contain a few surprises.
